The effect of strain rate on susceptibility of TB6 titanium alloy to adiabatic shear was investigated through dynamic loading of hat-shaped specimen of TB6 titanium alloy by using a split-Hopkinson compression bar at room temperature. The following results are obtained: all four groups of specimens exhibit obvious strain hardening effects at a strain rate of 1 950-2 510 s-1; with the rising of adiabatic temperature, adiabatic shear bands (ASBs) form in all four groups of specimens due to thermoplastic instability; there is no obvious deformation gradient in the transition zone between the matrix and the adiabatic shear band due to the influence of impact load and material grain size; the equiaxed grains with size of 100 nm are formed in the hot shear band due to rotational dynamic recrystallization. By observing the metallographic structure, characterizing the adiabatic shear sensitivity, and calculating the expansion energy, it can be inferred that the susceptibility of TB6 titanium alloy to adiabatic shear increases with the increase of strain rate.
